This application is a continuation of U.S. patent application Ser. No. 11/186,919, filed Jul. 22, 2005, (now U.S. Pat. No. 7,227,107), which is a division of U.S. patent application Ser. No. 10/371,194 (now abandoned), which claims priority under 35 U.S.C. §119(e) to provisional application 60/358,726 filed Feb. 25, 2002 and entitled COOKING FACILITATOR, each application is incorporated herein by reference.
Reference is made to disclosure document number 512,113 filed by inventor Don McLemore on May 28, 2002 for a GAS FLOW TIMER, and its contents are incorporated herein by reference.
The present invention is directed at a cooking facilitator with countdown timer means and means for providing food characteristic information relevant to cooking time (such as food item weight and/or thickness) and means for providing or setting the appropriate cooking time based on pre-established parameters such as a formula, memory table or the like. The cooking facilitator is preferably portable so as to render it well suited for use in an outdoor cooking environment as in the case of deep frying a turkey. Also, the present invention preferably features a configuration which is associated with the food item well suited for use with the facilitator such as a turkey configuration for deep frying turkeys. The facilitator also includes a signal generator which signals completion of a set cooking time with the signal preferably being of a type also associated with the food item being cooked. The invention is also directed at a gas flow timer.
There exists countdown timers that are intended for indoor kitchen use while the user is cooking or baking. For example, “egg timers” are well known with the earlier versions often having a mounted hour glass design which was turned to initiate the timing of the egg boiling. There is also known mechanical countdown timers such as that available from Lux Products Corporation of Mt. Laurel, N.J., under the registered trademark MINUTE MINDER.®.
There has also been introduced cooking timers that feature added electronics in place of at least some of the mechanical components such as the above described MINUTE MINDER® timer. An example is found in U.S. Pat. No. 5,933,391 which is incorporated herein by reference. U.S. Pat. No. 5,933,391 features an LCD display, piezo buzzer and an electric contact/logic control circuitry with microprocessor.
In the toy field there is found examples of sound emitting means which include integrated circuit chips connected to a speaker as shown in, for example, U.S. Pat. No. 4,875,886. Prior art sound emitting means include means which play back a stored sound pattern, such as a melody or a voice; the stored sound pattern being stored on magnetic tape, on an optical or magnetic disk, or electronically in a circuit.
There also exists a variety of cookware, both indoor and outdoor. These include cookware for deep frying, steaming and boiling food items. Deep frying large poultry items such as whole turkey with an outdoor cooking apparatus has gained in popularity as a way of cooking which is both quicker than baking and less susceptible to drying out the food. Outdoor cooking apparatuses often include a stock pot which is received on a gas (e.g., propane) cooker stand. In deep frying a whole turkey, a pot that is sufficiently sized to receive a whole turkey is utilized in conjunction with a sufficient level of cooking oil. To avoid exposure to the oil (e.g. splashing or actual contact), turkey securement arrangements have been developed, such as those shown in U.S. Pat. Nos. 5,896,810 and 5,813,321. A further example of a cooking system well suited for use in deep frying a turkey can be seen in the “TURF N' SURF” cooking system of Masterbuilt Manufacturing Inc. of Columbus, Ga., and reference is made to U.S. Ser. No. 10/005,311 filed Dec. 7, 2001 which is incorporated by reference herein and illustrates a cooking apparatus of Masterbuilt Manufacturing Inc.
The present invention provides a cooking facilitator which is preferably portable and well suited for use as both a timer and cooking process facilitator having particular usefulness with cooking objects which have a characteristic associated with establishing a cooking time such as the weight of a turkey in the case of deep frying a turkey or the thickness of a steak in deep frying the same, to name a few. The present invention provides means for providing to an operator cooking time information through the input of a food characteristic such as the input of, for example, the weight of an object to be cooked which has a weight associated cooking time. A preferred embodiment of the present invention features a pre-set time/weight dual scale which allows an operator to set/visualize a cooking time period by simply adjusting the timer to a weight value of the object to be cooked, which is often readily ascertainable from the food packaging. For example, most whole poultry items such as whole turkeys are sold by the pound and this information is clearly set out on the packaging.
The present invention is preferably a portable device to facilitate use with outdoor cooking environments such as deep frying whole turkeys. The source of power can be either solely mechanically based such as through the winding of a spring for time countdown and/or time completion signal generation, or can be battery based for either or both of the timer countdown means and signal generation means. The means for interrelating the cooking time with the a food characteristic (e.g., weight or thickness) of the object being cooked is either preset and fixed such as in a non-adjustable dual scale indicia arrangement featuring a time scale and particular type of cooking object weight scale with the interrelationship being, for example, formula based or predetermined through testing. For example, a turkey fryer weight scale which is based on the following formula:
(Product lbs Weight×3 Minutes)+5 minutes=total cooking time
An example of a fixed scale arrangement features a time scale with interrelated weight scale in one unit type (e.g., pounds) and a second unit type (e.g., grams) and/or a multi-food type scale such as one featuring a time scale in conjunction with a weight scale for a first type of food (e.g. a turkey) and a second fixed scale for a second type of food type (e.g. chicken, beef and/or pork products). The time scale is based on the maximum potential cooking time anticipated for the product(s) for which the invention is intended for use. For instance, in view of the quicker cooking times associated with deep frying turkeys a scale that is less than 90 minutes (and more preferably less than 80 and more than 50 minutes) with minute intervals designated and groupings identified (e.g. 5 minute intervals) would be well suited for the purposes of the present invention. Also, the means for interrelating cooking time and cooking weight with respect to the timer of the invention can be based solely on weight indicia with the timing component being a set feature of the timing mechanism of the present invention (e.g. in the case of a mechanical timer, the gearing and spring types involved relative to the movable or adjustable adjustment means such as a lever or dial without the need for a displaying of the time scale).
The present invention also features an adjustable cooking facilitator suited, for example, a plurality of food types such as through use of a mechanical adjustment feature such as a replaceable indicia scale (e.g., a plurality of scales which can be interchangeably positioned relative to a fixed time scale with indicia indicating the type of food product associated with that scale). An alternate embodiment of the invention includes adjustment means which are electronically based. An example of an electronically based adjustment system of the present invention includes a stored group of cooking time formulas or a library of correlated cooking time and characteristic values whereupon the entry of a weight provides for the determination of the cooking time for an inputted food product (or vice versa for situations where the desired product weight information is desired such as prior to purchase and the desired cooking time is known). Suitable display means can be provide relative to both inputable information and any information output as well as toggle or option switching means relative to different cooking products or other options to be afforded by the facilitator. In a formula based system, the formula can also include one or more additional variable inputs such as the cooking temperature to be used (e.g. an option of cooking within a temperature range which may be suitable for a particular type of cooking method and product; an example of which is 350 to 375° F. for turkey frying).
The present invention also preferably includes a signal generator for signaling when a time period has expired. This can include a variety of signaling means which can be picked up by the cook's senses. Examples include, for instance, sound generation, mechanical movement, light signals and/or smell generation. The signal generation can be a one time signal that either can be continuous until the operator shuts off or designed to run through a predetermined period before shut off or can be a repeating signal with a time delay in between each signal generation period.
The present invention also includes a preferred embodiment which interrelates the timer support and/or signal with a particular type of food item to be cooked associated or most associated with the timer of the invention. As an example, a timer to be utilized with outdoor deep fat turkey frying that includes a representation of a turkey (preferably a comical or non-realistic depiction of a turkey) with a support base. The timer device in a preferred embodiment features the turkey configuration with the timing means and/or weight information providing means held by the turkey configuration. The invention features a variety of means for such holding including a fixed/integral relationship such as in a unitary shell molding technique with time and weigh indicia applied (e.g. painted) or provided as an integral component such as integrally molding the information in the turkey configuration (preferably a plastic hollow shell) with an adjustable dial supported by the shell. Alternately, the timer means can be held in a pocket or otherwise releasably attached for removal (this removal and potential for reinsertion or reattachment also provides a means for altering or adjusting the type of timer being utilized). A further example would be the depiction of a cow, steer or bull (preferably exaggerated/comical) configuration with a countdown timer included.
The base can also include one or more cavities under the present invention providing battery receiving means and/or signal generation means and associated wiring. For example, a two battery support cavity with corresponding contacts and wiring to a signal generation means such as a sound producing IC chip and speaker. If mechanical movement or light generation is involved (either in place of or in conjunction with the sound generation), than a motor and associated mechanical linkages and/or gearing can be provided (e.g., internalized within the shell or main body of the configuration). Similarly the wiring or the like for the light generating means can be internalized and used in conjunction with internally and/or externally lighting such as LED's.
A preferred embodiment of the invention also preferably features sound generation which is associated with the configuration such as the noise a turkey makes for the above noted turkey configuration noted above. Also, while a real or realistic representation of the noise a turkey makes can be utilized (e.g. an actual recording), the present invention, particularly when a comical turkey representation is involved, features a non-real or not entirely realistic sound such as a “gobble-gobble” sound generation which is producible by an IC chip and speaker combination or some other form of sound generation. As a further example, the “moo” sound associated with beef cattle. Also, if mechanical movement is involved; this too is also preferably interrelated with the food type most intended (such as tail feather movement and/or beak movement associated with a turkey, or the lowering of a long steer's head and horns with a stamping of a hoof).
Under the present invention cooking is facilitated by taking much of the guesswork out of the cooking process and ensuring both a proper cooking time and avoiding overcooking.
In the embodiment shown in
The present invention also features means for interrelating 35 a food characteristic with the countdown device, which in the
In a preferred embodiment configuration 26 is a representative configuration which provides a correlation with the food product such as the representation of a turkey as shown in
With reference to
The signal generation means 60 of the present invention can include a variety of signaling means which can be picked up by the cook's senses. In addition to the sound generation means noted above further examples include, for instance, mechanical movement, light signals and/or smell generation. The signal generation can be a one time signal that either can be continuous until the operator shuts off or designed to run through a predetermined period before automatic shut off or can be a repeating signal with a time delay in between each signal generation period. The additional signal generation embodiments described above can either be used alone or in any combination.
If mechanical movement or light generation is involved (either in place of or in conjunction with sound generation, for example), than a motor and associated mechanical linkages and/or gearing can be provided (e.g., internalized within the shell or main body of the configuration). Similarly the wiring or the like for the light generating means can be internalized and used in conjunction with internally and/or externally positioned lighting such as LED's.
The base provides a good location for storing any electrical components, but alternate arrangement are also contemplated including reliance on one or more cavities in the mid-body 48 or some alternate location or relationship. Also while a preferred embodiment of the present invention is a portable non-plug in type device, an alternate embodiment of the invention can include an electrical plug in arrangement (with suitable electronic circuitry designed for household plug in use). The preferred portable nature of the present invention and the use of micro-electronics allows main body to relatively small (e.g. 2 to 12 inches in height). A larger alternate embodiment of the present invention is also contemplated e.g. 12 inches to 3 feet which can be provided as a yard decoration adjacent an outdoor cooking area. In such case the relative timer/main body dimensions can be altered and different material choices may be more appropriate to handle continued presence in the outdoor environment (chosen amongst the large assortment of various material available in addition to plastics such as ceramics, cement, metals, etc.)
A permanently outdoor cooking facilitator can include additional weather protection features such as added sealing and modified positioning of any holes such as an all internal or under region on the main body for the speaker holes 66. The weight of the device is also chosen in association with its size and intended use (e.g., a hollow plastic large cooking facilitator can be provided with extra base ballast or means for adding ballast (e.g., a sand pouring cavity))
The signal generation can be a one time signal that either can be continuous until the operator shuts off or designed to run through a predetermined period before shut off or can be a repeating signal with a time delay in between each signal generation period.
If mechanical driver 72 is opted for, suitable gearing and the like is preferably added to move a component of the representative configuration.
In similar fashion, light system 74 can be used as a signal generator either alone or in conjunction with another signal type. The lighting arrangement is preferably a high awareness signal such as a lighting of plumage feathers formed of translucent or transparent material or an altering of colors of the same. The light source shown can also be used as a general lighting source such as relative to the dials and indicia or to provide the cooking facilitator with the additional function of a light source to facilitate low light level cooking environments (e.g., a light bulb provided behind a transparent dial and/or display platform on a larger sized facilitator for example or with a flashlight arrangement for hand held sizes).
The rear view of
As an example of a cooking sequence associated with that illustrated in
Provide a turkey (e.g., a whole bird, preferably 16 lbs maximum with a range of 5 to 20 and a sub-range of 8 to 16 being illustrative)
The amount of oil needed in the cooking pot is determined by the size of the turkey (note the present invention's food characteristic setting means can also provide a general guidance scale as to the amount of oil typically needed with a particular bird to help facilitate providing the appropriate amount of cooking oil to the pot—which can include a liquid volume scale such as a quart or liter scale linked to the weight scale and preferably to a particular type of cooking pot (although a plurality of different dimensioned cooking pot parameter levels can be displayed with the facilitator)). To determine the appropriate amount of oil, the turkey, wild or domestic, is placed into a cooking pot preferably after placement into a fryer basket or onto a turkey support. Following placement of the bird into the pot, the pot is filled with water until the butt of the bird is covered. Then the bird is suspended from the pot, allowing all water to drain from the bird back into the pot. Once this is complete the level of the water is marked. The water is then emptied from pot and the pot refilled with oil to the marked line. Three inches of space should be provided from the top of the pot to the top of bird. Prior to cooking, the bird should be thawed out and free of any excess water and any plastic pop-up thermometer. Prior to insertion into the cooking oil the turkey is preferably covered with, for example, Cajun spices both outside and on the inside cavity. The oil temperature is then brought to 350° F. by adjusting the burner flame and monitoring a cooking thermometer inserted into the oil (e.g. a thermometer clipped to the top edge of the pot). The cook keeps a close watch on the temperature as it is important to maintain as close to 350° F. as possible while cooking. The turkey is then placed in the basket or on the rack with the legs of bird pointing up. The cook then slowly lowers the bird into the 350° F. grease or oil (wearing a cooking glove for splatter protection).
Within a range of before or shortly after (e.g. within 3 minutes) inserting the turkey into the pre-heated cooking oil, the cook sets the cooking facilitator of the present invention by inputting the characteristic relied upon (weight in this instance) to set the cooking time. The count down is then initiated and when the set cooking time is complete the signal generator is activated to inform the cooker the cooking period is complete in accordance with the preset value. The present invention precludes the cook having to consider the question of “when did I start cooking” which can be difficult to remember particularly for long cooking periods and is very common in outdoor cooking settings where a timer might not be readily viewable or available. Once the timer goes off (a time down or manual shut off), the cooker is turned OFF and the bird removed slowly with the grab hook, allowing the oil to escape the bird inside and out.
In addition, to facilitating matching a proper cooking time with weight of the bird (or other food characteristic), the cooking facilitator helps in planning the cooking process ahead of time and, as noted above, can also help provide guidance as to other cooking characteristics such as how much oil should be purchased to ensure coverage of the turkey chosen following the water marking test.
Provided below is one example of the manner in which the cooking facilitator of the present invention can provide the cooking time relative to a specific weight through use of, for example, a suitable formula for the cooking process intended. As noted above, a fixed time scale can be associated with a fixed weight scale with a preferred embodiment featuring circumferentially arranged scales with a turn dial with radial pointer for helping to show the appropriate (e.g., formula based) cooking time by visualization, along a common radial line, the tick marks for the respective scales. Other arrangements are also covered under the invention such as a lever with linear scales, etc. If the above noted formula of (W×3 min.)+5 min equals total cooking time is utilized then, then the scale would inform the cooker that an 11.5 lb turkey would have a cooking time of 39.5 minutes which would be set by the cooker simply by adjustment of a dial, lever or other countdown positioning means to the weight value of the bird.
Example: Cooking a 11.5 pound turkey 3 minutes per pound plus 5 minutes, for a total cooking time of 39.5 minutes. (11.5 Pounds×3 Minutes=34.5+5 Minutes=39.5 minutes). When the cooking facilitator signals the turkey is done, the burner is turned off and the turkey removed from the basket (preferably after a period where it is lifted out of the oil above the top of the oil in the pot to allow for the dripping off of the cooking oil such as through use of the capture hook arrangement described in the aforementioned U.S. Ser. No. 10/005,311). The turkey is then removed from the cooking pot after sufficient drainage and then allowed to cool for eating. Note: If the turkey should float before the cooking time is complete, this does not mean the turkey is done. Thus, the cooking facilitator helps avoid a premature removal by ensuring conformance with the time parameters established above. For pheasant, Cornish hen, chicken, and quail, the same time formula can be relied upon (e.g. a highly universal one such as described above) or a different formula for the particular type of food product can be set either with a multi-product cooking facilitator (e.g., one with multiple scales) or with reliance on a specially designed cooking facilitator with only a single scale and with a configuration suggesting the type of food item that particular cooking facilitator is best suited.
Under the process of the present invention it is possible to deep fry more than one bird at a time, but it is generally recommended that in calculating the total cooking time using the facilitator of the present invention, the cook should not total the weight of more than one bird. For example: For three Cornish hens at 2 lbs. the facilitator should be set based on 2 lbs and not the sum of 3 birds (a scale value such as one based on the above formula where the cooking time information would be 6 minutes ((2 lbs weight times 3 minutes) plus 5 minutes for a total cooking time of 11 minutes).
As a further example of some alternate indicia/information that can be provided by a facilitator of the present invention, the invention features a scale for cooking one or more turkey breasts (an example of different cuts of the food item type) as opposed to a whole turkey. In this situation the cook would follow the directions for a whole bird, but with a different cooking period involved determined by the cooking facilitator of the present invention. For example, a breast formula for use in establishing a cook time/weight interrelationship for the cooking facilitator can be based on a formula of cooking for 7 minutes per pound of breast meat plus 5 minutes to get a total cook time. (3 pounds of turkey breast×7 minutes per pound=21 minutes+5 additional minutes=26 minutes total cook time). Thus an additional scale can be provided under the present invention either alone or in conjunction with a whole fryer scale.
As shown in
As an alternate embodiment,
Also, as a characteristic for steak which is highly determinative of its cooking time in a deep fry, for example, the cooking facilitator 134, for example, includes means for inputting (e.g. dial or lever movement or an electronic circuitry input button or the like) the food characteristic (thickness in half or quarter inches for example with a suitable range for anticipated thicknesses) and there is also preferably provided the means for conveying the countdown time associated with the input characteristic such as a fixed or movable time scale as in
Timer 136 in
As shown in
A variety of valve and valve closure means are featured in the present invention such as ball valves, cylinder valves, butterfly valves, plunger and diaphragm valve structures. The valve utilized is contained and protected by housing 170 and is preferably one that placed in a closure state by mechanical means interrelated with the setting means (e.g., dial or handle), although the present invention also features both electrical timers and electrical or electrical mechanical combinations (e.g., electronic clock signals when time period expires leading to a triggering of a solenoid valve closure means as an example of an electrical based system deriving power, for example, from a battery). A mechanical means, however, is preferred for the setting, count down and valve closure means of the present invention both in view of the potential harsh environment and avoiding having to rely on the owner to change batteries for functioning of the timer. Although the present invention also features a fail close biased valve such as a spring biased solenoid valve wherein the solenoid moves open against the spring biasing closure when the setting means is away from off position but shuts off the valve when the setting means reaches the off setting or when there is a lack of power in the system due to, for example, lack of sufficient battery power.
Solenoid generally comprise of a wire coil and a movable plunger that seats against the coil. When current is applied to the coil, an actuating magnetic field is created. Solenoid valves are electro-mechanical devices that use a solenoid to control valve actuation. Electrical current is supplied to the solenoid coil, and the resulting magnetic field acts upon the plunger, whose resulting motion actuates the valve. Standard models are available in both AC and DC voltages and can be battery operated. Another characteristic of solenoid valves is whether their normal operating state is open, or closed, when not energized.
The sensor wire W can include a plug in head which is received in a reception cavity in the housing which is electronically connected to the solenoid to provide the electrical circuit which is activated when the temperature is reached. Alternatively, an electrical signal such as an one generated by a battery operated thermometer sensing system can be used with an alternate valve closure triggering means such as a small motor adjustment in a trunnion supported ball valve (e.g., overriding or releasing a hand twist countdown device when a preset temperature is reached).
It should be emphasized that the above-described embodiments of the present invention, particularly, and “preferred” embodiments, are merely possible examples of implementations, merely set forth for a clear understanding of the principles of the invention. Many variations and modifications may be made to the above-described embodiment(s) of the invention without departing substantially from the spirit and principles of the invention. All such modifications and variations are intended to be included herein within the scope of the disclosure and the present invention and protected by the following claims.
